At present, there are many ways to cultivate beans, and the implementation of hanger cultivation in winter beans can better improve the lighting and ventilation conditions. Compared with traditional small bamboo poles or tree branches, the use of plastic ropes to make an anterograde hanger has the following main advantages: :
The first is simple and convenient. No matter at the front edge of the greenhouse, or at the lower sides of the arch-shaped greenhouse, it is easy to set up a single-line forward hanger and lead-in.
The second is to improve ventilation and light transmission. The distance between the rows of hangers can be adjusted by moving the sleeves tied to the antegrade wire tightened on the east-west tension wire, and the distance between the adjacent stems of the peer can be adjusted by moving the distance between the hangers tied to the straight wires the distance between. In this way, the main distribution of the pods can be adjusted to improve the lighting and ventilation (air) conditions. In addition, nylon ropes (threads) or plastic film hanging ropes are transparent and have no shading effect on the crops in the shed.
The third is that the hanger is more suitable for three-dimensional cultivation of densely planted beans in greenhouses.
Fourth, it is convenient for the zigzag hanger to fall and fall.
It is recommended to set up a hanger before the bean sprouts are dumped. The specific method is:
When the main vines of bean sprouts are extended to 20-30 cm, artificial vines should be set to assist the shelves. In the Shouguang type winter warm plastic greenhouse, there are three east-west tension wires (24 or 26 wires) specially for hangers. On the east-west tensioned hanger wires, according to the north-south direction of the beans on the shed field Line spacing, set the anterograde hanger wire (usually 14 gauge wire).
On the antegrade wire, hang the nylon rope or plastic film rope that hangs near the ground according to the pitch of the plant (埯) in the bank. The lower end of the hanging rope is fastened to a short bamboo pole deeply inserted between the plants, and the short bamboo pole has a height of 20-30 cm on the ground.
The density of planting bean horns in the shed is 2500 pots per acre, each with 4 trees, a total of 10,000. When setting up a hanger, two hanging trees can be used with a hanging rope, or one hanging rope can be used for each.
When the vine is artificially introduced to the hanger, the bean stalk can be easily tied to the hanging rope. And pay attention to often check after the vine is thrown, and artificially assist the bean sprouts that have not been able to climb on the sling by themselves, and turn it right on the rope. When the vines are put on the shelf, because of the high humidity in the greenhouse, the vines are delicate and easy to break, it is better to choose noon or afternoon on a sunny day, and avoid vines on the cloudy or morning.

Green and functional cosmetics are more and more favored by people. As plant extracts are more and more widely used in cosmetics, more and more varieties are used. Compared with traditional cosmetics, cosmetics prepared with plant extracts as active ingredients have many advantages, such as overcoming the shortcoming of traditional cosmetics relying on chemical composite products, and making the safety of products higher; Natural components are more easily absorbed by the skin, making the effect of the product more significant; Functional more prominent, etc. Therefore, the application of plant extracts in cosmetics is the inevitable trend of market development. In addition, plant extracts have many obvious advantages, such as wide source and targeted mechanism of action. Especially with the progress of modern extraction technology and analysis technology, its effective ingredients and related mechanisms of action have been gradually discovered and confirmed by people, in the sunscreen, whitening, anti-aging, sterilization and other aspects of significant efficacy, can be widely used in various cosmetics. Therefore, the application prospect of plant extracts in cosmetics is very broad.
